심리운동 관점의 산림치유 프로그램이 중년의 숲 경험에 미치는 영향
김윤수(Kim, Youn-Soo),이병창(Lee, Byung-Chang) 한독심리운동학회 2021 심리운동연구 Vol.7 No.2
본 연구는 심리운동 관점의 산림치유 프로그램이 중년의 숲 경험 정도에 미치는 영향을 알아보기 위해 진행되었다. 심리운동 관점으로 숲에서 산림치유적 요소를 적용하여 프로그램을 구성하였으며, 중년을 위한 심리운동 관점의 산림치유 프로그램이 숲 경험에 어떤 영향을 미치는지 연구하였다. 이를 위해 경험의 3가지 요소(인지적 자유, 내적 동기, 인지적 유능감)로 이루어진 총 9개 문항의 숲 경험척도를 이용하였다. 본 연구의 측정도구는 숲 경험척도로 2017년 김윤수가 개발한 9문항의 척도로 Deci와 Ryan의 자결성 이론을 근거로 하고 있다. 2019년 9월 2일~9월24일 40~60대 C시에 거주하는 성인을 대상으로 산림치유프로그램을 진행하였다. 1차에 2회기 1회기당 40분씩 총 12회기 심리운동관점의 산림치유 프로그램을 실시하였다. 심리운동 관점의 산림치유프로그램이 인간을 이해하고 환경에 적응하는 신체 기능에 대한 폭넓은 이해를 제시하고자 한다. This study was conducted to investigate the effect of a forest healing program from a psychomotor perspective on the forest experience level of middle-aged adults. The program was constructed by applying forest healing elements in the forest from a psychological exercise perspective, and the effect of a forest healing program from a psychological exercise perspective on the forest experience level of middle-aged adults was studied. This study used the Forest Experience Scale with a total of 9 items consisting of three elements of experience - cognitive freedom, intrinsic motivation, and cognitive competence. It was developed by Kim youn-soo in 2017 and based on Deci and Ryan’s theory of self-determination. From September 2 to September 24 in 2019, the forest healing program from the perspective was conducted for middle-aged adults living in the C city in their 40s and 60s. A total of 12 sessions were carried out, each session lasted for about 40 minutes and two sessions were conducted a day. This study attempted to present a broad understanding of the body s ability to understand humans and adapt to the environment through the forest healing program from a psychomotor perspective.

우리나라의 출생 성비는 자연 상태에서의 출생 성비(natural sex ratio at birth)로 추정되는 105를 초과하고 있는데, 그 원인 중 하나로 남아선호사상으로 인한 인위적인 출산이 있다(e.g. 임신중절 등). 본 연구에서는 임신 중절 없이 남아를 낳을 때까지만 출산을 하려는 가정(family)들의 존재가 출생 성비를 높이는 데에 기여하는지를 알아보기 위하여, 이러한 가정들과 출생 성비(sex ratio at birth)의 관계를 분석하였다. 그 결과, 남아 한 명을 낳을 때까지만 출산을 하려는 가정의 수가 무한으로 발산할수록 출생 성비는 자연 상태에서의 출생 성비에 확률적으로 수렴하는 것을 알 수 있었다. 즉, 남아를 낳을 때까지만 출산을 하려는 가정들의 존재는 출생 성비에 영향을 미치지 않음을 확인하였다. The sex ratio at birth of South Korea is exceeding the natural sex ratio at birth, which is estimated to be about 105. One of the reasons of high sex ratio at birth is due to sex-selective abortion which is caused by strong son preference. The main objective of this study is to identify whether the families which are trying to bear children only until they acquire one son contribute to high sex ratio at birth. As a result, we obtain the theorem that if the number of such families diverge, the sex ratio at birth converges to the natural sex ratio almost surely. Therefore, we conclude that the existence of the families which are trying to bear children only until they receive one son does not affect the sex ratio at birth.

수침목재의 재질분석에 관한 연구-미시형태적 변화를 중심으로
김윤수,최광남,KIM, Yoon-Soo,CHOI, Kwang-Nam 국립문화재연구소 1986 保存科學硏究 Vol.7 No.-
Micoromorphological alterations of sea-waterlogged woods by marinemicro-oragnisms were investigated by the light and scanning electron microscopy as a part of serial investigations on the shipwrecked materials which were excavated at the sea shore of Wando-Kun, southern coast of Korea in 1984.Deterioration of sea-waterlogged wood by marine microorganisms were varied with the wood species. The degree of deterioration even in the same wood specieswas different according to the part where it was in mud of sea-water. However, the resistance of Torreya nucifera over the marine organisms was marked. Deterioration in cell wall may be classified into three types; thinning of cell wall, separation of secondary wall from compound middle lamella and tunneling of cell wall. Thinning and separation were frequently observed, while the tunneling was rare. Among the wood cell elements of hardwoods, vessel wall was the least deteriorated. The difference degree of degradation of cell wall constituents and the accumulation of inorganic substances in cell lumen indicate that some factors to be considered for the conservation treatment were discussed. The kinds of marine microorganisms invading and/or inhabiting in wrecked wooden ship were also discussed.

In most mammals, levels of lactase are high during infancy but by the time adulthood is reached these levels of lactase are deficient. So far, the exact mechanism involved in the appearance and disappearance of lactase is not known. The present experimental study describes the digestive enzymatic adaptation of disaccharidase to the substrate in diet composition in order to investigate whether the mere presence of corresponding substrate in the diet suffices to stimulate disaccharidase or not, probably by $quot;turning on$quot; which encodes for the synthesis of these enzymes. Our experimental studies suggest that lactase activity in the newborn of the rat immediately after normal birth is at a peak and remains there through the lactating period; however, disappearance of lactase was observed four days after weaning. It reappeared in seven days after the rat, which had been fed for 150 days on a sucrose diet, was shifted to a lactose diet, However, the activity was weaker than that of the lactating period, indicating that enzymatic adaptation of latose to the substrate in diet may be related. On the other hand no surcease levels were found throughout the lactating period, but the levlel of surcease rose independently of the sucrose diet intake after weaning, indicating that the sucrose in the diet did not seem to influence the surcease activity at all.

다양한 생물반응기 형태가 인삼(Panax ginseng C.A. Meyer) 부정근의 생장과 Ginsenoside 생산에 미치는 영향
김윤수,한은주,백기엽,Kim, Yun-Soo,Hahn, Eun-Joo,Paek, Kee-Yoeup 한국식물생명공학회 2004 식물생명공학회지 Vol.31 No.3
생물반응기의 형태에 따른 인삼부정근의 생장과 ginsen-side의 생산능력에 대하여 조사한 결과, 원형의 상부와 하부에 5 cm의 bubble column을 가진 bulb type bubble bioreactor (BU)에서 건물중은 41.92 g으로 가장 많이 증가하였으며, cylindric tube bioreactor (CT)에서 건물중이 38.55g으로 가장 낮게 나타났다. 이들 두 생물반응기의 초기 kLa 값은 BU 생물반응기에서 6.98 h$^{-1}$로 가장 높게 측정되었고, 반대로 bubble column이 없는 CT 생물반응기에서 5.25 h$^{-1}$으로 가장 낮게 측정되었다. 그러나 이와 같은 초기 kLa값의 차이는 부정근내의 이차대사산물인 ginsenoside의 함량에는 영향을 주지 않는 것으로 나타났다. 또한 BU 생물반응기에서 bubble column의 길이를 기존의 5 cm에서 10 cm로 연장시켰을 때, 초기 kLa값이 6.52 h$^{-1}$에서 7.80 h$^{-1}$로 증가하면서 인삼부정근의 생장을 42.13 g에서 50.30 g으로 약 16% 증가시킨 것으로 나타났다. The type of air lift bioreactor affected the root growth in ginseng adventitious root cultures. Among bioreactors used in this experiment, bulb type bubble bioreactor (BU) was the best to increase root growth (41.92 g dry weight). The kLa value representing the oxygen transfer capacity from medium to explants (6.98 h$^{-1}$ ) in BU with 5 cm bubble column was higher than other bioreactors. On the other hand, cylindric tube bioreactor (CT) without bubble column resulted in minimum root growth (38.55 g dry weight) and kLa value (5.25 h$^{-1}$ ). Furthermore, the root growth (50.30 g dry weight) in BU with 10 cm bubble column more increased than 5 cm bubble column. However, the kLa value do not affected the secondary metabolite such as ginsenosides. These results show that the bubble column in air lift bioreactor increase kLa value and increased kLa value stimulate the growth of ginseng adventitious roots.

진공미량저울을 써서 벤젠과 그 유도체들의 흑연화카아본블랙, Spheron6 위에서의 흡착등온 곡선을 얻었다. 이로부터 각 흡착질의 Spheron6 위에서의 분자단면적을 계산했다. 이 값들을 비교하여 흡착질이 Spheron6 표면에 흡착될 때, 벤젠고리는 흡착체 표면에 평행으로 되며 흡착질 분자는 이 평면 상에서 제한된 각도로 회전하고 있음을 밝혔다. Adsorption isotherms of benzene and its derivatives on Spheron 6, a graphitized carbon black, are obtained using a sensitive quartz beam microbalance. From the isotherms the molecular area of each adsorbate on Spheron 6 is calculated on the basis of nitrogen area of 16.2 $A^2$. the results show that the molecules of each species are adsorbed on Spheron 6 with the planes of benzene rings lying flat on the surfaces and doing hindered rotation.
